How do I shield a Smart meter”
A Smart meter is a radiofrequency (RF) emitting device that the utility company has installed on your gas or electric meter. The RF signal emitted transmits information back to the utility company about your gas or electric usage. The signal is intermittent, but operates 24/7. Usually, the utility company will not permit you to completely block this transmission. However, you can shield your body and your living space to minimize the amount of RF exposure you receive.
If you are also concerned about the magnetic field emissions (due to the presence of electric current), see magnetic shielding material and the magnetic shielding FAQ….
